Hello all, I am new on this list but I use Fractint since 1994. I have difficulty in include/understand English and I use a translator. I would like to propose two new models of "Triternion". T_Ikenaga and T_Lambda. The formulas triternion are mysterious. I read that those would be 6-d. I am not a mathematician and I does not know exactly what that means. Here two formulas.
